HOLDER FOR SEWING-MACHINE BBBINS, 65o.

Specication of Letters Patent.

i Application led February 8, 1916. Serial No. 77,111.

To all fau/wm it may concern.'

Be it known that 1, HUGH RAMSEY HAM- IL'roN, a citizen of the United States, residing at Webster, in the county of Worcester' and State of Massachusetts, have invented new and useful Improvements in Holders for Sewing-Machine Bobbins, &c., of which the following is a speciiication.

This invention relates to a holder for tubular articles, such as discoidal bobbins for sewing machines, the bobbin being composed of a cop tube and an annular body of thread wound thereon.

The invention is embodied in a holder adapted to store a plurality of bobbins, and also to store the discarded tubes after the thread has been removed therefrom, the holder being portable and ot such construction that it may be supplied, with a charge ol bobbins, to a sewing machine operator at the beginning of a working period, and used at the end of said period as a means of determining the number of bobbins used, the o 3- f erator being expected to turn in the holder with a number of spent tubes or of tubes and unused bobbins correspondingl to the number 01 bobbins issued.

Of the accompanying drawings forming a part of this specication:

Figure 1 represents a perspective view of a holder embodying the invention;

Fig. la represents a perspective view of one of the spindle-obstructing stops;

Fig. 2 represents a longitudinal section of the holder;

Fig. 3 represents an end view showing a modication Fig. 4 represents a discoidal bobbin;

Fig. 5 represents a perspective view of the cop tube of said bobbin.

he same reference characters indicate the same or similar parts in all the views.

In the drawings, 12 represents a base adapted to rest loosely on a sewing machine stand or table and support the rod and storage spindles hereinafter described, in a position perpendicular to the table.

13 represents a central rod attached at one end to the base and extending perpendicular thereto.

To the base are attached perpendicular storage spindles 14 arranged equidistant perspective view of a from the rod 13, four spindles being preferably provided, although the number may be greater or less than four.

Each spindle is formed to permit a plurality of cop tubes 15 to be strung upon it, the tubes being either empty, as shown by Fig. 5, or provided with a winding 15a of thread, as shown by Fig. 4, which represents a complete bobbin.

To the outer end oi" the rod 13 are pivoted a plurality of stops 1G, which in the preferred embodiment ot' my invention, shown by Figs. 1l` 2 and 3, are composed oi independent strips of spring steel, each peu forated at its inner end to turn on a pivot 17 formed on the outer end of the rod. Each stop is formed to bridge the space between the rod 13 and one of the spindles 14, and is provided at its swinging end with an opening 18 constituting a coupling member adapted to engage a complemental coupling member 19 formed on the outer end of a spindle 14, the resilience of the strip holding said members in yielding engagement with each other.

The number of stops is preferably less than the number of spindles, as indicated by Fig. 1, which shows tour spindles and three stops. This arrangment enables one spindle to be left unobstructed while the others are obstructed by the stops.

At the commencement of a working period the described holder may be issued to a sewing machine operator with one or more of the spindles charged with bobbins, which may be retained until wanted by a stop or stops 16. The bobbins may be withdrawn one at a time as fast as required, and the spent tubes 15 may be dropped upon the unobstructed spindle until the latter is lled, this spindle being then obstructed by a stop, and another spindle unobstructed to receive other tubes. At the end of the working period the operator returns the holder. If the operator has not lost or stolen bobbins during said period, the number of tubes, either spent or in unused bobbins, will equal the number of bobbins issued.

It is obvious that the number of stops may be equal to the number of spindles, as indicated by Fig. 3.

Having described my invention, I claim:

A holder for sewing-machine bobbins and Patented lbiay 15, 1.9.17.

central rod attached comprising a hase, a thereto, a series of storage spindles attached t0 the hase and having reduced outer ends equidistant from the rod,

stops pivoted the stops being aper Copies of this patent may be obtained for I' and independently movable rod-obstructing to the outer end of the rod,

tured to receive the refive cents each, by addressing' the duced outei` ends of the spindles and being arranged to spring downwardly so as nor-y mally to maintain engagement between the l stops and the spindles therebeneath.

In testimony whereof l have aiXed my signature.
